The information presented to the D inputs is stored in the flip-flops on the LOW-to-HIGH Clock (CP) transition. This device is functionally identical to the 74F374 except for the pinouts. Features ■ Inputs and outputs on opposite sides of package allowing easy interface with microprocessors ■Useful as input or output port for microprocessors ■Functionally identical to 74F374 ■3-STATE outputs for bus-oriented applications Ordering Code: Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.

Page 3 2 7 4 F 5 7 4 Unit Loading/Fan Out Functional Description The 74F574 consists of eight edge-triggered flip-flops with individual D-type inputs and 3-STATE true outputs. The buffered clock and buffered Output Enable are common to all flip-flops. The eight flip-flops will store the state of their individual D inputs that meet the setup and hold times requirements on the LOW-to-HIGH Clock (CP) transition. With the Output Enable (OE) LOW, the contents of the eight flip-flops are available at the outputs. When OE is HIGH, the outputs go to the high impedance state. Opera- tion of the OE input does not affect the state of the flip- flops.
